In Resale Price Maintenance (RPM) contracts, the manufacturer specifies the resale price that retailers must charge to consumers. We study the role of using a RPM contract in a market where demand is influenced by retailer sales effort. First, it is well known that RPM alone does not provide incentive for the retailer to use adequate sales effort and some form of quantity fixing may be needed to achieve channel coordination. However, when the market potential of the product is uncertain, RPM with quantity fixing is a rigid contract form. We propose and study a variety of RPM contracts with quantity fixing that offer different forms of flexibility including pricing flexibility and quantity flexibility. Second, we address a long‐time debate in both academia and practice on whether RPM is anti‐competitive in a market when two retailers compete on both price and sales effort. We show that depending on the relative intensity of price competition and sales effort competition, RPM may lead to higher or lower retail prices compared to a two‐part tariff contract, which specifies a wholesale price and a fixed fee. Further, the impact of RPM on price competition and sales effort competition is always opposite to each other. © 2006 Wiley Periodicals, Inc. Naval Research Logistics, 2006  相似文献

承包商的努力程度直接决定了装备的制造成本。为有效激励承包商降低装备制造成本,提高装备采购效益,基于里昂惕夫劳资博弈模型建立了成本分担定价方式的装备采购博弈模型。并在承包商边际效用非线性和定价方式多变量的假设基础上,分别对价格、成本、承包商努力程度和承包商效用之间的关系进行了研究,对原模型进行了拓展,为定价方式中参数的确定提供了量化方法。  相似文献

在Internet中传输实时多媒体需要性能良好的拥塞控制机制来确保一定的服务质量。应用实时传输协议RTP的反馈报文的信息,开发了使用参数自适应变化的AIMD拥塞算法来消除拥塞,最终得到了一种改进的单播多媒体自适应拥塞控制算法。经OPNET网络仿真分析,在各种丢失率环境下,算法的发送速率平滑性等性能表现良好,较好地满足了网络多媒体的传输特性需求。  相似文献

Abstract

This paper explains and assesses the UK experience with determining prices and profitability for non-competitive defence contracts. Three periods are considered, namely pre-1968, the 1968 Profit Formula Agreement and the changes introduced in 2014. Two cases of ‘excessive’ profits were major determinants of the 1968 Profit Formula Agreement; but continued dissatisfaction with the 1968 Agreement led to changes in 2014. The historical overview of UK experience provides a basis for understanding current UK policy and offers insights for other countries facing similar policy challenges. A critique is presented of UK policy on single source pricing and profitability.  相似文献

Procurement of advanced technology defence equipment requires appropriate contractual arrangements to achieve efficient R&D investments. This paper analyses the optimality of target‐cost and fixed price contracts and shows that target‐cost pricing can achieve a first best where both fixed‐price contracts and cost reimbursement fail to do so. The main message of this paper is that in incomplete contracting optimality may sometimes be achieved by arrangements which combine several formulae which, individually, would fail to achieve efficiency.  相似文献

E‐commerce platforms afford retailers unprecedented visibility into customer purchase behavior and provide an environment in which prices can be updated quickly and cheaply in response to changing market conditions. This study investigates dynamic pricing strategies for maximizing revenue in an Internet retail channel by actively learning customers' demand response to price. A general methodology is proposed for dynamically pricing information goods, as well as other nonperishable products for which inventory levels are not an essential consideration in pricing. A Bayesian model of demand uncertainty involving the Dirichlet distribution or a mixture of such distributions as a prior captures a wide range of beliefs about customer demand. We provide both analytic formulas and efficient approximation methods for updating these prior distributions after sales data have been observed. We then investigate several strategies for sequential pricing based on index functions that consider both the potential revenue and the information value of selecting prices. These strategies require a manageable amount of computation, are robust to many types of prior misspecification, and yield high revenues compared to static pricing and passive learning approaches. © 2006 Wiley Periodicals, Inc.

The existing product line design literature devotes little attention to the effect of demand uncertainty. Due to demand uncertainty, the supply‐demand mismatch is inevitable which leads to different degrees of lost sales depending on the configuration of product lines. In this article, we adopt a stylized two‐segment setup with uncertain market sizes and illustrate the interplay between two effects: risk pooling that mitigates the impact of demand uncertainty and market segmentation that facilitates consumer differentiation. Compared to downward substitution, inducing bidirectional substitution through product line decisions including quality levels and prices can yield greater risk pooling effects. However, we show that the additional benefit from the risk pooling effect cannot compensate for the reduced market segmentation effect. We demonstrate that the presence of demand uncertainty can reduce the benefit of market segmentation and therefore the length of product lines in terms of the difference between products. We also propose three heuristics that separate product line and production decisions; each of these heuristics corresponds to one particular form of demand substitution. Our numerical studies indicate that the best of the three heuristics yields performance that is close to optimality. © 2015 Wiley Periodicals, Inc. Naval Research Logistics 62: 143–157, 2015  相似文献
